To all whom it may concern: nected by means of Be it known that I, Josnrn E. l i iLLnris, Member 12 is formed with an opening or a resident of Pittsburg, in the county of A slit 14 and member 11 with a similar openlegheny and State of Pennsylvania, have inmg 15, each adapted to receive a projecting portion of the wire-gauze constituting the strainer proper.

When corrugations,

vented certain new and useful Improvements in Strainers or Coffee-Pots, &c., of which the following is a specification.

My invention relates to improvements in strainers for coffee-pots, tea-pots, and similar receptacles, and more particularly to a new and improved detachable auxiliary strainer for receptacles of the class above such for example as 3 on the pot shown, are employed, it is necessary, in order to have the frame fit closely to l the wall thereof, to provide corresponding corrugations 16 on the side contacting members 7.

set forth. The bulging or swelled strainer proper or In the accompanying draw ng which illusscreen 17, preferably made of wire-gauze, is trates an application of my invention, Figattached to the supporting-frame by having portions 18 and 19 respecthe openings 14 and the members 8 and 9 the projecting tively passed through 15 and then bent over of the inner frame.

. The strainer-proper is formed with a marginal rim or edges 19 which are bent over against and lie in close contact with the top, bottom, an side members of the inner frame. The screen or strainer proper extends or bulges inwardly from its supporting-frame and comprises a substantially flat horizontal lower portion 20, slightly inclined and substantially flat sides 21 and a slightly tapering and curve front 22.

By making the strainer proper of the form shown, I provide a construction by which the coffee-grounds, tea-leaves, etc. will not clog the strainer and prevent a free outlet of the liquid. hus, in the form shown, when the pot is tilted in the operation of pouring its contents, the coifeegrounds, or tea-leaves, or a ortion of the same will move into contact with the strainer and will bank up against the horizontal portion 20, thus leaving considerable space on the sides 21 and all of the curved front uncovered or unobstructed to a free passage of the liquid contents from the receptacle into the spout.

The supporting-frame structure together with the strainer-proper is detachably secured to the receptacle by means of a springattaching-member 23. Member 23 is secure to the frame at one end only and in the form illustrated, it is attached to the lower-member 9 by passing its end through an opening ure 1 is a vertical sectional view of a coffeepot with my invention applied thereto, shown partly in elevation; Fig. 2, a part lan and a part sectional view; Fig. 3, a perspective view of the supporting-frame of the strainer; Fig. 4, a detail sectional view taken on line H of Fig. 3; and'Fig. 5 a

lan view of the screen or strainer proper.

As illustrated, 1 designates a cofiee-pot provided with the usual spout 2 and having its wall perforated at the base of the spout as shown at 3. In the example shown, the pot is formed with corrugations 4, extending entirely around the body of the pot, but it is of course understood that the pot per se is not my invention.

My improved strainer may be applied to and used in connection with any style of coffee or tea-pot or similar receptacle having a perforated wall located adj acent to the spout.

The strainer as illustrated and as pre-o ferred comprises a supporting-frame structure adapted to fit over the perforationsv 3 and is made to correspond with the contour of the interior surface of the wall of the receptacle, adjacent to the base of the spout. As shown the support for the strainer proper comprises an integral metallic structure consisting of an outer frame forme with an upper contacting member or surface 5, a lower member 6, and side contacting members 7, all adapted when the strainer is applied to the receptacle to fit closely to the wall of the receptac e. Located back of the contacting members 5, 6, and 7 and corresponding in contour therewith is an inner or supplemental frame consisting of an up- 24 therein and soldering it to said member, per member 8, a lower member 9, and side as particularly shown by 1 1 The sai members 10.
